Elastic Waves in Anisotropic Laminates FROM THE PUBLISHER
Ultrasonic non-destructive evaluation (NDE) plays an increasingly important role in determining properties and detecting defects in composite materials, and the analysis of wave behavior is crucial to effectively using NDE techniques. The complexity of elastic wave propagation in anisotropic media has led to a reliance on numerical methods of analysis-methods that are often quite time-consuming and whose results yield even further difficulties in extracting explicit phenomena and characteristics.Innovative and insightful, Elastic Waves in Anisotropic Laminates establishes a set of high-performance, analytical-numerical methods for elastic wave analysis of anisotropic layered structures. The treatment furnishes a comprehensive introduction, sound theoretical development, and applications to smart materials, plates, and shells. The techniques, detailed in both the time and frequency domains, include methods that combine the finite element method (FEM) with the Fourier transform approach and the strip element method (SEM). These -methods can also be used for expediently finding the Green's function for anisotropic laminates useful for inverse problems related to wave propagation, and methods for inverse analyses, including conjugate gradient methods, and genetic algorithms are also introduced.The text is complemented by many examples generated using software codes based on the techniques developed. Filled with charts and illustrations, Elastic Waves in Anisotropic Laminates is accessible even to readers from non-engineering backgrounds and offers a unique opportunity to discover methods that can lead to an understanding of the dynamic characteristics and wave motion behaviors ofadvanced composite materials.
FROM THE CRITICS
Booknews
Liu and Xi (both engineering, National University of Singapore) present the first text devoted entirely to modern analytical- numerical methods for elastic wave analysis of anisotropic layered structures. The text includes applications to smart materials, plates, and shells; techniques which combine the finite element method (FEM) with the Fourier transform approach and the strip element method (SEM); and an expedient method for inverse problems related to wave propagation. Intended mainly for senior university students, postgraduate students, and engineers in civil, mechanical, geographical, aeronautical engineering and engineering mechanics. Requires only an elementary knowledge of matrix algebra, the Fourier transform, and the linear theory of elasticity. Annotation c. Book News, Inc., Portland, OR (booknews.com)
